Knowledge only becomes power once you’re capable of putting the theory into practice
Being powerful implies a mutuality of influence, both sides being able not only influence the other, but also having influence over how they are, in turn influenced. That’s what they call “Interaction”!
In other words:
“Only in interaction does knowledge become visible and relevant.”
The same goes for talent, as well as other personal qualities.
Your cosy conviction that you are “a talented person” remains a fantasy until you put it into action.
